The Hypertext Transfer Protocol (HTTP), a key building block of the World Wide Web, has succeeded to enable information exchange worldwide. Since its first version in 1996, HTTP/1.0, the average number of inlined objects and average total bytes per webpage have been increasing significantly for desktops and mobiles, from 1-10 objects in 1996 to more than 100 objects in June 2014. Even if the re...

introduction: macroprolactin is a significant cause of misdiagnosis, unnecessary investigation, and inappropriate treatment in patients with hyperprolactinemia. its frequency has not been clearly established due to technical difficulties in identifying it. most laboratories and clinicians are unaware of macroprolactin interferences in prolactin assays. materials and methods: a comprehensive lit...

A line ` is a transversal to a family F of convex polytopes in R if it intersects every member of F . If, in addition, ` is an isolated point of the space of line transversals to F , we say that F is a pinning of `. We show that any minimal pinning of a line by polytopes in R such that no face of a polytope is coplanar with the line has size at most eight. If in addition the polytopes are pairw...

To manage a big event require tracking in real time the movement of crowds. Solution based on mobile network data analysis are effective, but expensive. Obtaining comparable results by analysing public social stream has a clear commercial potential, especially considering that, being able to access also the content of a micro-post, the analysis can also track the attention of crowds.

In this paper, we present some preliminary studies on reducing the emittance of the Hefei light source II (HLS-II) storage ring by redistributing the synchrotron damping partition factor using a Robinson wiggler. The studies demonstrate that it is possible to reduce the emittance by 50% using a 2-meter long wiggler on a rematched lattice. This encouraging result suggests a feasible option to si...

Suppose that n buyers each want one unit and m sellers each have one or more units of a good. Sellers post prices, and then buyers choose sellers. In symmetric equilibrium, similar sellers all post one price, and buyers randomize. Hence, more or fewer buyers may arrive than a seller can accommodate. We call this frictions. We solve for prices and the endogenous matching function for finite n an...

Password sharing is widely used as a means of delegating access, but it is open to abuse and relies heavily on trust in the person being delegated to. We present a protocol for delegating access to websites as a natural extension to the Pico protocol. Through this we explore the potential characteristics of delegation mechanisms and how they interact. We conclude that security for the delegator...

We show that if a line ` is an isolated line transversal to a finite familyF of (possibly intersecting) balls inR and no two balls are externally tangent on ` then there is a subset G ⊆ F of size at most 12 such that ` is an isolated line transversal to G. We generalize this result to families of semi-algebraic ovaloids.
